McKinney police officer resigns after video catches him manhandling teens at a pool party. Update!

A police officer in McKinney, Tex., who was seen on video pulling his gun on teenagers in swimsuits and shoving a young black girl’s face in the ground at a pool party has resigned, the police said Tuesday. 

Cpl. David Eric Casebolt, who had been placed on administrative leave after the episode on Friday, remains under investigation, Chief Greg Conley said at a news conference. The corporal will keep his pension and benefits, the police chief said. 

“Our policies, our training, our practice doesn’t support his actions,” Chief Conley said. “He came into the call out of control, and as the video shows was out of control during the incident.” 

The video was taken on a cellphone and posted to YouTube, where it set off another in a recent series of debates involving race and police tactics. The police said Corporal Casebolt and other officers were responding to a call about a fight and a disturbance at a community pool in Craig Ranch, a racially diverse subdivision north of Dallas.

I have actually received some interesting responses to my mentioning of this incident in the post about that South Carolina cop being indicted for shooting the unarmed black man in the back.

Most people are suitably outraged, but there has been a very vocal minority that has attempted to defend the police officer's response, claiming that the kids were not listening to his commands, that they were disrespectful, and that DJ was tweeting invitations to everybody in the area, not just those originally invited by the teens.

So some of that, or all of that, might be true, but here is the raw video of this officer's response.

(Here is an updated version since the other one was removed from You Tube.)

You tell me, was he justified?

Update: So here is a link to some of the conservative excuse making concerning this incident. Including Megyn Kelly saying that the victim was "no saint either."
